Magnesium lines as filed

PureBulk.com Magnesium Hydroxide retains 1 magnesium-related rows in NIH DSLD 23167, including 1 rows selected for the primary serving, from label 2013-06-25, examined 2026-09-13.

Magnesium (Form: as Magnesium Hydroxide)

Selected primary serving

The elemental amount comes from the selected magnesium line. A salt named under another nutrient does not make that nutrient's quantity an elemental magnesium value. Distinct unresolved primary amounts remain ambiguous; they are not added together.

What the package works out to

PureBulk.com Magnesium Hydroxide works out to 250 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2013-06-25, calculated 2026-09-13.

Arithmetic using the label's own serving, not intake advice

Serving size as filed1000 mg
Servings per package250
Daily servings in the label instructions1
Days per package at the label's own serving250 days

Days = filed servings per container ÷ filed servings per day. If the label gives a frequency range, the largest frequency gives the shortest duration. Cost per serving = observed item price ÷ filed servings; cost per label-day multiplies this by the filed frequency. This follows the label's own instructions; it is package arithmetic, not intake advice.

Percent daily value · observed and computed

The label's percent daily value, recomputed

PureBulk.com Magnesium Hydroxide files 1 magnesium percent-daily-value entries in NIH DSLD 23167; the check below applies the group-specific references in 21 CFR 101.9 to its 417 mg primary serving, calculated 2026-09-13.

Declared values and current-reference arithmetic
Group as filedDeclaredReferenceRecomputedDifference
Adults and children 4 or more years of age104%420 mg99%5 percentage points

Percent daily value = declared elemental mg ÷ the group's reference mg × 100, rounded to an integer. The adult and age-four-plus reference is 420 mg. Historical labels can use earlier references; a difference does not establish a filing error. Full-record entries may cover multiple serving sizes, so this table identifies the primary-serving basis explicitly. Group references and interpretation.
